Resumen: The acceptance of bio-based products by consumers is one of the fundamental pillars to achieve the integration of a circular economy model in society. This article analyses the results obtained in a large-scale survey on the social acceptance of bio-based products, especially those obtained from Absorbent Hygiene Products, where a statistical analysis of the data collected is performed to establish rules of thumb and conclusions on the factors considered most significant for consumers in their purchasing decisions. The study was carried out in four European countries, and the sample population covered different age ranges, genders and economic statuses. The main findings are that the most critical factors relate to price, quality and ease of use, but other factors, such as environmental benefits, composition and origin of materials, also affect bio-based products. In addition, this study concludes that most people do not understand some important aspects related to bio-based products, and product information and communication channels need to be improved. Therefore, purchasing strategies for bio-based products should focus on addressing these shortcomings, making the decision to buy bio-based products a quick and easy action.
